DOI: 10.1007/s10714-019-2549-7
Abstract: Supermassive black holes (SMBHs) are found in the centres of most galaxies. Their masses, and hence their gravitational potentials, are negligible compared with those of the host galaxy. However, several strong correlations between SMBH masses… read more here.

DOI: 10.1016/j.newast.2016.08.009
Abstract: Abstract The observational cosmology with distant Type Ia supernovae (SNe) as standard candles claims that the Universe is in accelerated expansion, caused by a large fraction of dark energy. In this paper we investigate the… read more here.

DOI: 10.1017/pasa.2025.10122
Abstract: Abstract Impulsive radio signals such as fast radio bursts (FRBs) are imprinted with the signatures of multi-path propagation through ionised media in the form of frequency-dependent temporal broadening of the pulse profile, commonly referred to… read more here.

DOI: 10.1038/s41586-024-08210-5
Abstract: Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after the Big Bang, many of which seem to be overmassive relative to their… read more here.

DOI: 10.1051/0004-6361/202039238
Abstract: We use 3,213 Active Galactic Nuclei (AGNs) from the $\it{XMM}$-XXL northern field to investigate the relation of AGN type with host galaxy properties. Applying a Bayesian method, we derive the hardness ratios (HRs) and through… read more here.

DOI: 10.1093/mnras/stab2538
Abstract: The co-evolution between central supermassive black holes (BHs), their host galaxies, and dark matter haloes is still a matter of intense debate. Present theoretical models suffer from large uncertainties and degeneracies, for example, between the… read more here.

DOI: 10.1093/mnras/stac461
Abstract: An m = 1 lopsided asymmetry is common in disc galaxies. Here, we investigate the excitation of an m = 1 lopsidedness in host galaxies during minor mergers while choosing a set of 1:10 merger… read more here.

DOI: 10.1093/mnras/stae1953
Abstract: Current and future Type Ia Supernova (SN Ia) surveys will need to adopt new approaches to classifying SNe and obtaining their redshifts without spectra if they wish to reach their full potential. We present here… read more here.

DOI: 10.1093/mnras/stae293
Abstract: Type Ia supernova (SN Ia) cosmology analyses include a luminosity step function in their distance standardization process to account for an observed yet unexplained difference in the post-standardization luminosities of SNe Ia originating from different… read more here.

DOI: 10.1093/mnras/stx007
Abstract: Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff--Riley (FR) type I and II sources. FRI/II and compact radio galaxies have also… read more here.

Abstract: We propose a novel methodology to select host galaxy candidates of future pulsar timing array (PTA) detections of resolved gravitational waves (GWs) from massive black hole binaries (MBHBs). The method exploits the physical dependence of… read more here.
